Revert r323008 and its conversion of e1000/iflib to using SX locks.

This seems to be missing something on the 82574L causing NFS root mounts
to hang.

Continuation of lock cleanup in e1000.

Post-cold sleep instead of DELAY when waiting for firmware.

Convert softc mutex to an SX lock. Change all waits to sleeps
once interrupts are enabled (and it is safe to sleep).

Merge ^/head r294961 through r295350.

Update em(4) to 7.6.1; update igb(4) to 2.5.3.

chipsets.)

Update em(4) to 7.6.1; update igb(4) to 2.5.3.

Major changes:

- Add i219/i219(2) hardware support. (Found on Skylake generation and newer
chipsets.)
- Further to the last Skylake support diff, this one also includes support for
the Lewisburg chipset (i219(3)).

- Add a workaround to an igb hardware errata.
All 1G server products need to have IPv6 extension header parsing turned off.
This should be listed in the specification updates for current 1G server
products, e.g. for i350 it's errata #37 in this document:
http://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/ethernet-controller-i350-spec-update.pdf

- Avoton (i354) PHY errata workaround added

And a bunch of minor fixes, as well as #defines for things that the current
em(4)/igb(4) drivers don't implement.
